I had the same problems and the solutions about deleting everything and
installing in a different folder and making sure you are an administrator do
NOT work. I tried them all. There is one solution that DOES work though but
it involves extensive editing in the Registry, so maybe not for everyone.
I didn't come up with this solution myself but someone called Dan figured it
out and posted it in the microsoft.private.security.spyware.install group.
Here is a copy of his post

I'm running XP Pro SP2, in a workgroup, not a domain. I
have multiple logins, all members of the Administrators
group. Only the user who installed the software can use it.
Billions of the zillions of registry entries MSAS uses (the
HKCR\CLSID\* entries are ok) have permissions that allow
the installing user and the System account access to the
registry keys. The Administrators group is NOT granted
access -- which is what causes the other logins to fail
with the uninformative "Unexpected error; quitting" message.
In a fit of anal-retentive pique I manually edited the
registry to grant Administrators Full permission to the
HKCR\Microsoft.AntiSpyware.Trust*,
HKLM\Software\Classes\Microsoft.AntiSpyware.Trust*,
HKCR\gc*, and HKLM\SOFTWARE\Classes\gc* keys. This solved
the problem (though it took me 30+ minutes) -- until I next
upgraded and/or reinstalled.
So this problem is NOT just about Administrator accounts,
it is also about the installer setting inappropriately
restrictive permissions on the registry keys. At the very
least it should be possible to have an installer that gave
permissions to Administrators rather than a single member
of the Administrators group...
If you are not familier with editing the Registry you shouldn't do this, but
it did work for me
